One high-performance, dual-tube muffler combines the best features of both a glass-pack muffler and an original equipment muffler...;effortlessly! Heavy-duty 16-gauge aluminized case and nipples. Has reverse. Muffler blanks without nipples available in 24" overall lengths. Select overall length and inlet & outlet I.D.

"Good solid muffler. I've used them in the past for custom built systems on cars, pick-ups & sports cars. They always sound good, perform well & hold up well. I'm glad they're still available to use on my latest project, which happens to be a 2001 Civic, as I'm not a big fan of the tuner cans."

"I just installed these two mufflers on my RX7 . They sound nice , just the right amount of tone for this car. Not a glass pack though, as advertised, it has baffles inside , no glass ."

"These mufflers are very tough and are easily modified for so many applications! Great sound and nothing to burn out,so they last! Just wish they were not so expensive!!"

"I installed this on a 70's Bombardier sw48 sidewalk snowplow that has a 4.9 straight 6 Ford motor. When running ,the motor now backfires due to excessive back pressure. I will replace it with a true glasspack. I will keep this one around and maybe put it on my backhoe which has a 3cyl diesel."

Pros: Seems well constructed

Cons: Inside tubes too small for larger engines
